AP Chemistry Summer Assignment 2014-2015
Ms. Steiner
Woodland High School
To the AP Chemistry Student:
Welcome to my AP Chemistry class! I am looking forward to helping you gain a deeper appreciation for the
science of chemistry and how it impacts our lives. I hope you are looking forward to an exciting and
challenging year. Since you have elected to take this course, I assume you have the intelligence and motivation
needed to be successful. Your hard work will pay off, and you will find AP Chemistry to be a very rewarding
experience.
The Advance Placement Chemistry experience is designed to provide a full year of college-level chemistry, so
it places heavy demands on the student, especially in terms of the time commitment required. In fact, the
College Board suggests that students devote a minimum of five hours per week for individual study outside of
the classroom. The ultimate objective, of course, is to prepare you to take the AP Chemistry test in May 2015,
and in order to accomplish this, topics are covered very quickly. For this reason, most students take AP
Chemistry after they already completed a year of high school chemistry, since that provides them with a solid
foundation. In order to ensure the best start for you next fall, I prepared a Summer Assignment that reviews
many basic chemistry concepts.
It is important that everyone come to the first day of class well prepared! Extensive remediation is not an
option as we work towards our goal of becoming completely prepared for the AP Exam in early May, so seek
help early if you are experiencing difficulties.
Finally, I recommend that you spread out the Summer Assignment, rather than trying to complete it in the final
week of the summer! It takes time for a student to process, practice and subsequently learn chemistry at the
level necessary for success in AP Chemistry. Remember, AP Chemistry is an equivalent course to an
Introductory Chemistry college course, a full year program. Taking a college level course in high school is
difficult, and it requires commitment, hard work and time, but completion of a class like this is a great
investment in your education. Prepare yourself and arrive ready to learn!
You may want to use the following resources as help for the assignment that follows as well as throughout the
year. You may also find some of your own.

The following assignment will be reviewed in class beginning on the first day of school. I will take questions
on any problems you may have had from this assignment on the first few days of class. Therefore you need to
have your material with you on the first day. Please come prepared.
If you have any questions please feel free to call me at 678-201-6813 (if I do not answer, please leave your
name and a brief message and I will return your call) or email me at dsteiner@henry.k12.ga.us.
1. Review writing net ionic equations. You are expected to know the Solubility Rules on the attached page.
Memorize them!! We will have a quiz on Friday the first week of school over these.

2. Memorize all polyatomic ion formulas and charges. They are listed on the handout attached to this page.
Review these from Chem. I, as well. There are flash cards attached with some of them for you. Use them!
You will have a test over these on the third day of class. You also need to know the monatomic ions on the
attached page as well as be familiar with the important chemicals attached.
3. Complete the following assignment and bring to class with you on the first day of class.

AP Chemistry Summer Assignment
The following assignment is to be completed and brought on the first day of class.
DIRECTIONS: Solve the problems below, showing your setup, calculations, units and correct
Significant Figures (SigFigs). Neatly-written solutions are acceptable. (Points are deducted from AP
tests if correct SigFig rules and labels are ignored, so get into the habit of using them all of the time!)
1. Demonstrate that you know the correct use of significant figures (SigFig digits) by completing the following:
a. 738.90 m has _____ SigFgs.
b. 0.0304 g has _____ SigFigs.
c. 1.4 X 104 joules has _____SigFigs.
d. 1 dozen donuts has _____ SigFigs.
c. 40 mL has _____ SigFigs.
f. 800. m has _____ SigFigs.
2. A cylinder rod formed from silicon is 21.3 cm long and has a mass of 5.00 kg. The density of silicon is 2.33
g/cm3. What is the diameter of the cylinder? (The volume of cylinder is given by V = πr2h, where r is the radius
and h is the length.)
3. Calculate the following to the correct number of significant figures.
a. 1.27 g / 5.296 cm3 = ________________________
b. 12.235 g / 1.01 L = __________________________
c. 12.2 g + 0.38 g = _________________________
d. 17.3 g + 2.785 g = _______________________
e. 2.1m x 3.215m = _____________________
f. 200.1mi x 120 min = __________________
g. (17.6 + 2.838 + 2.3 + 110.77)g = _________________
4. A solid white substance A is heated strongly in the absence of air. It decomposes to form a new white
substance, B, and a gas, C. The gas has exactly the same properties as the product obtained when carbon is
burned in an excess of oxygen. Based on these observations, can we determine whether solids A and B and
the gas C are elements or compounds? Explain your conclusions for each substance.
